“For him to come in here and sit next to us and be comfortable with him and shooting the (bull) is pretty cool,” Dominguez said.

Grossman, who grew up in Houston cheering for Biggio’s Astros, listened attentively as Biggio spoke.

“It just shows the kind of guy he is in general,” Grossman said. “He’s a down to earth guy who is here to help us. It’s awesome just to sit and listen to what he has to say. I’m clinging on to everything he says. Just talking about baseball in general, talking about when he played and some of things he went through. Just listening to him is just a treat. We just sit there and enjoy it.”

September call-ups to be named Monday

Astros general manager Jeff Luhnow and manager Bo Porter are still debating which players will be called up immediately after rosters expand on Monday.

“I expect only one our two on the first,” Luhnow said of the first group of September call-ups.

No explanation for Carter’s power numbers

Chris Carter, who entered the night fourth in the American League in road homers with 17, isn’t sure why his home run numbers are so much better on the road than at Minute Maid Park.

“There’s no reason why there’s a difference. I think it’s just road cooking,” he said with a chuckle. “It’s definitely interesting to see the actual numbers of it, but there’s no correlation of anything.”

Carter entered the first game of the four-game series against the Mariners at Minute Maid Park on Thursday with a team-high 26 home runs. His 26 home runs are the most by an Astros since Carlos Lee had 26 in 2009.

The sample size isn’t big enough yet for the Astros to assume Carter will always have more home run power on the road.

“It’s just a fluke,” Bo Porter said. “It’s not like we have five or six years of information to go by. This is his first opportunity to play every day, and I think it’s just a fluke that he has better numbers on the road than he does at home.

“It’s one of those things where for me if you look at the dimensions of our ballpark and you see the short wall in left field and you say to yourself, ‘Wow if this guy was to actually pull the ball a little bit more at home maybe he’d hit 40 home runs instead of hitting 30. I think as time goes on, we’ll have more information.”
